IMPROVEMENT IN VENTILATED WATER-CLOSET BOWLS.

specification forming part of Letters Patent No. 187,408, dated February13, 1877; application filed January 3, 1876.

To all whom it may concern:

Be it known that I, HENRY OGDEN, of Providence, in the county ofProvidence and State of Rhode Island, have invented a new and ImprovedVentilated Water-Closet Bowl, of which the following is a specification:

My invention consists of a ventilating-pipe connection to the upper partof the bowl, but below the seat, whereby the bowl will be ventilatedwhether closed or in use, and there is a channel under the top flangeand above the water-inlet pipe for the vapor to pass around from thedifferent portions of the bowl to the exit-pipe unobstructed by thewater.

Figure l is a sectional elevation of my improved ventilated wash-bowl,and Fig. 2 is a plan view.

Similar letters of reference indicate corresponding parts.

A is the bowl, which may be of any approved kind, in the upper part ofwhich I arrange a ventilating-pipe connection, B, to be connected with apipe leading to the chimney, or fixed in any other way to produce adraft for ventilating the bowl whether in use or closed by the cover. dis a flange, which I propose to arrange on the inner surface of thebowl, above the inlet-pipe D, for water, and below the ventilatingpipe,to make a channel within which the obnoxious gases may collect, and aportion of the same be carried downward inliU the trap in the water asit enters the bowl, while that portion not so disposed of escapes intothe upper channel E, from whence it finds exit by means of the exit-pipeB.

Having thus described my invention, I claim as new and desire to secureby Letters Patent A water-closet bowl constructed with an upper and alower annular channel, the former connected with the exit-pipe, whilethe latter connects with the water-inlet pipe, substantially as and forthe purpose set forth.

HENRY OGDEN.
